Check the water quality and temperature. Warm water will not hold as much oxygen as cool water and goldfish are cold water fish. Ideal water temp is about 21 C. Use a home water test kit to check parameters. Ammonia and nitrites should read 0ppm (parts per million) and nitrates can be 40ppm or less. If you don't have a test kit, most pet stores or aquarists will test a sample for free or for a nominal fee. Ensure adequate filtration and oxygenation. Use a filter that will comfortably handle twice the volume of your tank. An airstone will increase oxygenation. A tank hood or cover is recommended to prevent fish from jumping out.
